47900 cm
General Formulas and Concepts:
<u>Chemistry</u>
- Base 10 Decimal System
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
0.479 km
<u>Step 2: Identify Conversions</u>
1 km = 1000 m
1 m = 100 cm
<u>Step 3: Convert</u>
<u />
= 47900. cm

Answer:
MnO4- + 5 VO +2 + 11 H2O = 5 V(OH)4+ + Mn+2 + 2 H+
Explanation:
The formula is easy:
Gram formula mass
----------------------------
Emprical Formula
So if we plug in our own numbers,
114.0
--------
57.116
We get an answer of 1.99, which rounds to 2.
Then, we distribute based off of our empirical formula.
2(C4H9) becomes C8H18.
Our molecular formula is C8H18.
